평면선형의 편구배에 대한 안전성 검토 : 고속의 도시부 가로를 중심으로 = The Investigation of Safety for Superelevation of Horizontal Alinement

다국어 초록 (Multilingual Abstract)

This study investigates fitness of horizontal alinement design elements that has been used in Korea. Those elements are analyzed in consideration of road environment, drivers' characteristics, and traffic condition. In addition, reformed superelevation formula is produced to be fit to the conditions in Korea by considering horizontal alinement design elements on the base of 'AASHTO'.
The results are summarized as follow
1. According to drivers' cognition analyzed by Factor analysis, drivers regard that road safety and horizontal alinement elements are the most important facts.
2. Superelevation value which is produced from radius of road curve in research area is shorter than standard superelevation value. Therefore, we should revise and supplement the standard superelevation in aspect of drivers' safety.
3. Superelevation value analyzed by 85 percentile running speed shows higher value than critical superelevation value used in Korea. So, we should upgrade the critical superelevation value.
